Confirmation of the Efficacy and Safety of Lenalidomide Oral Monotherapy in Patients with Relapsed or Refractory Diffuse Large-B-Cell Lymphoma: Results of An International Study (NHL-003)
Bibliographic record
Abstract
Abstract Introduction: Diffuse large-B-cell lymphoma (DLBCL) is the most common of the non-Hodgkin lymphomas (NHL). Patients with DLBCL who are not cured by treatment with R-CHOP chemotherapy or high-dose chemotherapy with autologous stem cell rescue have a poor prognosis. These patients reflect a clear unmet need in the treatment of DLBCL. A previous sub-analysis of a phase II trial (NHL-002) of lenalidomide in patients with relapsed or refractory DLBCL, demonstrated a 19% overall response rate (ORR) with a 7-month median duration of response (DR). A confirmatory international phase II trial (NHL-003) of single-agent lenalidomide was initiated for patients with relapsed/refractory aggressive NHL that had received at least one prior treatment and had measurable disease. Herein, we report the data from the DLBCL patients enrolled in this trial. Methods: Patients received 25 mg oral lenalidomide once daily on days 1–21 of every 28-day cycle and continued therapy until disease progression or toxicity. The 1999 IWLRC methodology was used to assess response and progression. Results: This report focuses on the 73 DLBCL patients that were enrolled and evaluable for response assessment. The median age was 67 (21–87) years and 49 (67%) patients were male. Median time from diagnosis to lenalidomide treatment was 2 (0–18.6) years, and patients had received a median of 3 (1–6) prior treatment regimens. The ORR to lenalidomide was 29% (21/73), with 4% complete response (3/73) and 25% partial response (18/73). Eleven patients (15%) had stable disease. The most common grade 3 or 4 adverse events were neutropenia (32%), thrombocytopenia (15%), asthenia (8%) and anemia (7%). Conclusion: These results of this international study confirm that lenalidomide is active in heavily pre-treated patients with relapsed or refractory DLBCL with manageable side effects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
